Pammegischia xiphydriae, new species : 



Q. Length 7.5 mm.; ovipositor about two-thirds the length of the ab- 

 domen. Black, with the first segment of the abdomen red, the second 

 joint of the front and middle trochanters and bases of their tibiae testaceous, 

 the remainder of legs black (all, however, are broken off about the middle 

 of the tibiae, so that I am not quite certain that the tips of the tibiae and 

 the tarsi are black). The head is quadrate, above smooth and highly 

 polishd with only a few scattered punctures ; in front, below the front 

 ocellus to the insertion of the antennae it is transversely rugulose ; while 

 beneath the antennae, except the lower inner angles of the malar space, 

 which are smooth and polished, it is closely irregularly punctate. The 

 mandibles are black with a rufo-piceous tinge basally. Palpi fuscous. 

 The thorax is rugosely punctate, the mesonotum with numerous trans- 

 verse ridges and with complete parapsidal furrows. Wings hyaline or at 

 most only faintly tinged, the stigma and veins being black or brown-black, 

 the first recurrent nervure being received by the second cubital cell only 

 a little beyond the middle, while the third cubital cell is more or less 

 divided into two by a spurious stump of a vein which originates from the 

 cubitus a little before the apex of the second recurrent nervure. All the 

 coxae are black and regulose, the hind pair being elongate and produced 

 beneath into a triangular process that extends far beyond the insertion of 

 the trochanters. The abdomen is highly polished, impunctate, except at 

 its extreme base, and shaped as in Aulacus or Pristaulacus, only that it is 

 not so distinctly petiolate, the first segment occupying fully half its whole 

 surface.
